1o all ywhom t may concern.' I

Be it known that I, CLAnENoE A. BisHor, a citizen vof the United States, residing in the city of New .Yor-k, borough of Brook- 'ly1 i, county of Kings, and. State of New York, have invented a certain new and useful Calculating Ap aratus, of which the following is a speciy catOli.

This invention is an apparatus for effectingcalculations, the same being intended, more particularly, for use in connection with insertible time cards for determining elapsed time and ,with insertible time and Wage cards -for calculating automatically the value of- Workmens Wages for variable periods at iiXed rates per hour.

An apparatus embodying the invention is intended .to receive the time card if elapsed time only .is to be calculated, or the Wage and time card if the time and Wage value are to be calculated, such card or cards being provided With an appropriate scale or scales, and said caidfor` cards being in-` sertible into the machine at certain periods or intervals of time, as for example when the Workman begins noi-k and completes Work on a particular job assigned to him. The machine is ot such construction that the workman cannot interfere with its operation, such as by insertinga too-l or Wire into it, Without ruiming the risk of detection, for the reason thatthe moving parts are i11- cased or housed to preclude access thereto; but to prevent movement of a time-driven member-by manipulation of the card to be operated upon, means are provided for lock- .iiig such time-driven member, such locking means being independent of the time-operated mechanism and being brought into action solely by manual manipulation of the card. e

A machine embodying the invention employs, among' other things, a card marking member and a card positioning member, one being movable relative to the other'by the time-operated mechanism. It is preferred to use. a punching or recessing device as the card marking member, said card punching o-r recessing device being positioned for manual operation at any 'time by the Workman. t

-The machine of this application is intended, more'particularly, orfcarrying out .the method disclosed in my copending application tiled June 9, 1910, Serial No.v 565,959,.,which eventuated in .Patent No larly asto that feature thereof which embodies the recessing device adapted to punch 1n a card a 'recess .of alpa'rticular form or shape, a time train, a movable guide operated or advanced by the time train and having the same foi-m in horizontal cross section as the recess punched in the card by the recessing de.- vice but in reverse thereto so that when the card is punched at the endof a given time and reversed; the said' guide will lill the recess.

According to one part 'of this invention, the card is inserted twice into the machine, and is punched or recessed a like number of times, one of such recesses or punches being produced in the card at the time the Workman starts Work on the assigned `iob, and the other at the time of completing work on the job. To indicate on the card the time of starting the Work and the elapsed time, and to insure that the card shall at the second punching operation be inserted into a beveled exposed card enoaging portion reversely positioned to the beveled operating punch of said punch mechanism, Whereby after the card is first punched to produce the beveled recess at the beginning ot the work, said card must be reversed prior to the second punching operation to indicate the completion ot the Work, which reversal of thecard enables it to be positioned at the secondpunching operation for the beveled. edged recess irst punched therein to registerand Contact properly with the beveled card-engaging portion of the card-retaining member.

In the apparatus to be hereinafter described as a preferred embodiment of the invention, the card punching member is normally stationary, Whereas the card positioning member ismovable, by clock mechanism of one form or another. The card retaining illeinber ,embodies a moving part and a plurality ci card-engaging elements movable with said moving part, said card engaging elements being positioned so that' operated mechanism for locking the card retaining member, said locking means being operable by manipulation of the card subsequent to its insertion. ln a preferred form of said locking means, the card engaging elements of the card positioning member are pivoted to the moving part and they are provided with means for frictionally clutching them to the guideway for said moving part. llhus, upon the inser tion of the card in a proper manner, for the purpose of punching it, the card engaging elements are ree from clutching ,engage ment with the guideway, but should the workman manipulate the card in any way so as to shift the normally inaccessible card positioning member Jfor giving an unaccrued increase in wages, then the displacement of the card, to even a slight degree, so acts on one or the other of the card engaging elements as to lock the card positioning member from movement, thus effectively and automatically frustrating the workmans surreptitious effort to secure an increased wage accounting.

The time-operated card engaging member is movable relative 'to the punching device at`predeterinined intervals and Jfor a predetermined distance, such. distances corresponding to the divisions of the inserted card, so that the recesses will be produced in a proper manner in the card. rlVhe total distance traveled by the card positioning niember is equal to the lengtho the scale on the card, so as to represent ordinarily the working hours of a day.

In a preferred form, the invention cmbodies means 'for automatically releasing the card positioning member from the time train the completion of the hours necessary to cover a working day, and for returning said card positioning member a starting position, but when it is desired to use the machine 'for calculating over-time, means are provided whereby the same mechanism may be used to produce recesses in a card for denoting overtime.

The means :tor returning the card posi-A tioning member to a starting position is a' drum actuated by a spring, the latter being placed under tension by the operation of the time train main spring, said drum being held fast to one of the timer train arbors by a notched wheel engaged by a pawl, but when fthe-pawl and wheel have turned a predef' Aconsists of means independentot the time termined distance, then the pawl is disengaged from the notched wheel and the spring drum becomes effective in automatically returning the card positioning member to the starting position. To adapt the mechanism for denoting over-time work on cards, z'. e. for the hours which elapse between the endingof the working day and the beginning of the next, a simple mechanism is employed in connection with said spring drum, notched wheel and pawl. Said mechanism is embodied in a second pawl and a second wheel, said 'second pawl being actuated by the second wheel so as to malte the drum fast with the arbor of the time train, whereby the second pawl'is effective in imparting the mo tion' of the time train to the card retaining member for operating` the latter in the intervalvdenoting over-time and before the next regular day begins, then the second pawl is automatically thrown out of operative position and the first named pawl is at the proper interval engaged with the notched wheel to place the machine in readiness for use during the regular working hours.

rlfhe invention embodies means for marking the inserted card so as to detect imsaid card in the machine at any one of the punching operations.

Other features of the inventions and the advantages thereof Will appear' Jrom the following detailed description.

'ln the drawings, Figure l is a sectional plan view of a calculating machine embodying the invention, lcertain parts being broken away and in section to show some of the mechanism contained within a casing. Fig. 2 is an inverted bottomplan view illustrating a part of the'card positioning member and a partei1 the time train coperating with said card' positioning member. Fig. 3 is a iront viewl, partly in vertical section, ci' the machine illustrated in Fig. l. Fig. 4 is a cross section' on the line 11i-ll of Fig. 3. Fig. 5 is an enlarged detail view of certain parts composing the card positioning member, illustrating one of the card engaging elements in a normal position by lfull lines, whereas the dotted lines illustrate a shifted position of the card engaging element for the purpose of locking or clutching said element tol preclude movement of the card retaining member.,4 F ig. (i is a fragmentary detail view of the punch. Fig. 7 illustrates diagrammatically -the position of the card positioning member, thepunch, and a card, the latter being insertedfor the first time into position relative to the card positioning member' and a punch for the purpose of producing thevrstrecess in the card. Fig S is alplantview of thev card' shown in Fig. 7 after' thev two recesses shall have been punchedlherein, sa-idfigure illustrating cerproper insertion of Locatie bodied in the machine when the'latter is to be used for punching overtime in the ards in addition to the use of the machine for the regular working hours during the day,

The base or casing A is provided with a .chamber a within which is contained certain so as to provide an opening b through which a marginal portion of a card is adapted to be inserted. The rear portion of the cover plate is intended Ato contact with the top so as to form an abutment for engagement by the edge of the card when the lat-ter is inserted below the cover plate and across the slot b in the casing, and this cover `plate precludes directI access to the card retaining member or to the mechanism contained within chamber' o of the base.

In. the machine shown, the punching mechanism is normally station-ary with respect to the base upon which said punching mechanism is mounted, whereby the punching mechanism -is exposed for convenient operation by hand.' Any suitable form of punch mechanism may be employed, but, as shown more 'particularly in Fig. 4t, the punch mechanism embodies a post o, a plunger .0 and' a spring c2. The post c is fixed in any suitable way to the top of the base. said post being constructed and positioned to overhang the cover plate B, and within this post is provided a vertical passage 03,'

within which operates plunge-r c. The plunger is shown as having a suit-able exposed operating` head c, and around said plunger is positioned the coiled spring c2. The lower part of the spring rests upon a shoulder provided in 'vertical passage c2 ot the post, whereas the upperpart ot the spring acts against a shoulder provided below the operating head 0*, said spring acting, mainly, to support the plunger in av raised position. rlhe plunger is. prevented from turning within the post by a stop pin c5, the latter serving, also, a means tor arresting the upward movement of the plunger under the impulse of spring c2. The plunger operates in an aperture provided in. the cover plate (as shown in Fig. e.) ,A and the lower part of this plunger is a punch or die C, shown more particularly in Fig. G. The punch ordie is in alinement vertically with a female die D, shown in Fig, fl as being countersunk in the top of the base so that the card may slip over said female die, the `.latter being, at one side of 4a, vertical slot o, and in register with said female die D is a discharge tube d leading into or through the base, for the purpose of discharging the cuttings which are produced by the operation of punch or die C upon the cards inserted into the machine.

rl`lie card retaining member shown in the preferred embodiment of the invention is movable relative to the punch.. member or mechanism, 'for which purpose a time train or cloelr mechanism is employed to impart movement. to said card retaining member, the detail'A oit 'which mechanisms will now be describ l The card retaining member is shown in ll`igs. l to 5, inclusive, as embodying a stationary track member e, a movable member c slidably litted to the track member, and a plurality ci card engaging elements E E. The stationary track member c is shown as a rod'or bar occupying a horizontal position within chamber a and extending the length of base n, the end portions of said rod being supported in end walls ot' the base, as illustrated in Fig. 3, whereby the track member occupies a horizontal stationary posi-- tion within the base. rlhe moving part e consists of a rod or bar suspended below the track; member and having upstanding forked or biturcated end portions ci, said end` portions oi the rod or bai Vembracing the track member e for the purpose of sliding freely thereon. The 'card engaging elements E E are supported on or carried by the forked end portions-.ofmovable part c, and these elements E E extend upwardly from thetracli rod so that the upper poitions ot said elements E E pass through slot in the top of the base, the extreme lupper end portion of said. element E extending upwardly into a guide channel c3 provided in under side of cover plate B, see l? ig. 4e. The upstanding .card engaging element E is provided with a part f adapted "jor engagement with an indicating clement of the card to be inserted, this part f being correspondingly shaped to the male Vdie or punch, but being positioned reversely thereto, for a purpose -which will presently apL pear. rlliis part of the card engaging element E is in the form of a linger provided with a raised shoulder, said lfinger extending rearwardly Vfrom the slot b and thev raised shoulder being inlthe same longitudinal plane the male die or punch, see AFig.

l. llhile various :forms of punch and the card engaging part ot element lll may be employed tor the purposes of this invention,

l use a male die or punch with a beveled ,properly positioned in the card retaining with an inclined side joining tivo parallel sides. Similarly, the card engaging linger f is a four-sided gure with an inclined side connecting the two parallel sides, but the .inclination ofthe' inclined side oi' the male die or punch is reversed to that of the 'card engaging iingenflVhen the card is lirst inserted into the maliine and the punch is operated a recess with a beveledside is cut in the card. Now when the card is inserted for the second punching or recessing operation, said card is preferably reversed in osition, that is, it must be turned end 'lor end and the face must be placed downward upon the to of the hase. This reversal of lthe card is tor the purpose of lirst punch mark or recess therein into register with the card engaging linger, the latter fitting in the punch or recess of the card so that the recess will fit accurately to the shape of said card engaging ringer; in other Words, the card 'cannot he inserted at the second punching or recessino operation un less the irst punch or recess has been initially produced in the card, andsaid card. is-reversed in order to bring the said first punch or recess into register with the card engaging linger. The space or distance hetWeen the' card engaging elements E E is equal substantially to the length ot' the card .to he used, and to enable the card to he member it is preferred` to employ a card of the form shown in Figs. 7 and 8 wherein the card X is provided with a permanent indexwhich is in the form ot' a notch reduced in one corner of said card.

Each element E E isprovided with a foot g, the width of which exceeds the width of the element, and this 'toot is recessed so as to produce two contact pointsg adapted to frictionally engage with theupper side of the track rod E. The toot g of each member is litted within the upper hilurcated part of one end piece e2 of the suspended rod or har c', and said foot g and Jthe hiiturcated end -piece'e2 are connected hy a piv- `otal pin g2, the latter passing through jaws provided by end piece e2 and through the foot g centrally of the latter. lt will he noted that the card engaging elements E El are vpositioned at the respective ends oft rod or bar e, and that the foot pieces g of said elements-'E E are connected pivotally with the bifurcated ends c2, said foot pieces g having reduced contact points g adapted to engage frictionally with the upper face ol fixed track bar e. The elements E E operate to suspend rod or bar c below the track rail c insuch manner that 'the rod or loar and the elements E E are free to move lengthwise of the track rail and with a minimum. amount of friction. The engagement of the points gf on the upstanding elements E E with the track brineino' thev D b .the change in position of the element E or E will bring one Contact point g of the card engaging element into forcible engage-- ment with the traclrrod, as a result of which the. tric'tinal contact between the point g will turn the element E or v orf-the card engaging element With 'the track A,

rod acts las a lock in precluding any movement of the card retaining member in the direction otv the length of said track rod. Brieliy stated, the foot g et each card en gaging element acts as a friction lock whensaid element is shifted by manipulation. oi

the card7 which lock precludes any move.

ment of the card retaining member. should an attempt he made by the Workman to in crease the value of the time or Wages indicated hy the record on the card. It may be said that the har or rod e acts as a carriage for the card engaging elements, the latter operating to suspend said carriage vfrom the track rod. The rictional contact between the reet g 01": the card engaging elements with the track rod may be adjusted ley movement. et certain screws g3 which are screwed into tapped openings provided in the rod or har c and adapted for ifrictional engagement with the under side of the track rod. Ey turning these screws in one direction the rictional contact between the points g with the rod or `bar may be Vtigl'itent-:d so as to preclude movement of the carriage and elements E E mounted thereon, but, obviously, suflicicnt slack or play should be permitted to secure freedom in the movement of the carriage and said elements E E on the track rail e.

-Any form o time train may loe employed 'for communicating' motion to the card ree taining member, and this time tfainisprovided with escapementwhichfis adapted tor control by a master clock se that a series o-sthe recording apparatus may he used on a single circuit controlled by said mastery rail retain said at f1.3 so that the tooth of the escapement L, and this escapement lever is provided will engage with a tooth of the pallet wheel with alf armature i et' an electromagnet I, the latter being in an electric circuit controlled by the master clock, the conductors of said circuit being indicatedat 27.

Mounted loosely on the lower part of one arbor, such as L, of the time train is a spool J adapted to turn independently of the arbor. Said spool is'provided at one end with a gear pinion j, and at its other end with a dislrj, the latter being provided with a notch or tooth jg. The gear j of the spool is in mesh directly with teeth j of a rack bar J', the latter being xedly secured to the end portion c2 of the carriage bar. The carrying arm K is secured rigidly to the lower extremity of arbor 7if by a screw 7c so that. the arm K will rotate with the post, and kon this arm K is mounted a feedpawl K by a pin 7a2. This pawl is pressed by a spring 7e3 into the notch jg of wheel y, and the pawl thus operates to make the wheel fast with the arbor, whereby the motion of the time train transmitted through `arbor 7i is communicated by the pawl and the notched disk to the gear y' for the purpose of moving rack J and the carriage, so as to impel-the card engaging elements E E .for apredetermined distance and at predetermined intervals sof time. When the disk and the pawl make one complete revolution, the heelZ of said pawl engages with a fixed post l, thereby disengaging the nose of the pawl from the notch in the wheel At this time the power of a return spring L becomes effective in turning spool J, the notched disk y" and gear y' in a/ backward direction for the purpose of moving the carriage and the card engaging elements back' to a starting position. The spring L is coiled around the spool, one end of the spring is attached to said spool and the other end of the lspring is anchored on the iixed pin Z; lVhen the carriage is in an operative position and is movable under the action of the time train controlled by the escapement so as to travel in the direction of the arrow of Fig. l, the power of the main spring Gr impels the time train and the carriage, and it is available, also, in placing the spring L under ,tensiong but upon the disengagement of pawl K from the notch i2 of wheel j, then the recoil of spring L acting upon the spool .l turns the spool, disk j', and gear y' in a reverse direction, for the purpose of returning the carriage and elements E E to starting position. lVhen the paWl is disengaged from the notch in the Wheel, the nose of said pawl is pressed by the spring into contact with the peripheral edge of said wheel. and thus the pawl is retained in position to enter the notch in the wheel at the proper-time.

Should the w rlnnan'-attempi to manipu late the'card for thepurposeof securing an unearned amount of time or wages, b v placing the card improperly in the machine, means are provided for producing on the card an-indication that said card was improperly placed within the machine. This means for detecting an unwarranted attempt on the part of the workman will be referred to as a detector device, and in a preferred form it is operated by the punch carrying plungervso as to produce perforations in a certain part of the card. The detector element is embodied in a vieldable barL M housed or contained within a. recessed is provided with depending pins or studs m arranged to enter apertures n provided in the top of the casing. The detector bar is adapted to be depressed when the plunger is operated to punch or recess the card by a stem N, the latter being shown in Figs, 3 and l as attached to the plunger head et, and the lower end of said plunger stem being adapted to pass through an opening 'n' provided in cover plate B at a point directly above thedetector bar M. The detector bar is composed, preferably, of spring steel so that it-will raise or lift. itself above lthe path of the card when the latter is inserted below the cover and across slot b. New, when the, punch" plunger is forcibly depressed, steniN will move downwardly and act upon the detector bar so as to force the latter toward the card, whereby pins m will perforate the card along a certain line provided on said card, the material cut out of the card passing through the openings n into chamber a of the base. TWhen the card is properly inserted two or more pins m will punch perforations in the card .along a certain predetermined line, but. should the card be turned at an angle or improperly positioned and the punch mechanism operated, then the pins m of the detector bar N will punch holes in the card not along the cation that the Workman4 has attempted to secure nnearned time or wage value by m properly positioning the card in the machine. y v

The card shown in Figs. 7 and 8 is one of several kinds which may be used, said card haring suitable spaces for the receptionof data pertaining to the date, the job number, the workmans name and nnmber, the operation to be performed, and various other printed matter. In addition to the notch a2 and the spaces m for receiving the desired data, the card is provided with a scale ,z denoting elapsed time. said scale being divided into hours and fractions thereof corresponding to the working hours of the day, and said scale reading progressively from the notched corner :c substan-` tially to the opposite end of the card In art m of cover B. This detector bar predetermined line, thus affording an indiioe addition to the foregoing elapsed' time scale, the card may or may not be provided with a second scale e having numerals. or other data indicating the starting time. Further more,.the card may or may not be provided with a scale having'numerals or other data to represent wages to be-paid to the workman based upon the time engaged upon a particular job and at a tixed rate ner hour, The wage scale should be divided into iractions corresponding to the divisions of the elapsed time scale, the two scales being in parallel columns. In addition to the fore- 'going'scale or scales, the card is provided with an indicating line e2 along which the card may be punched by the operation ot 'the pins m of detectorl bar M, two of said 'jpunch marks being indicated by the reien ence character z3. f

The o eration of theinvention as thus far described is as foilows: The main spring G is wound so as to place it under tension, and assuming that the carriage is at. the starting position for the card receiving elements to occupy the relation to the punching mechanism illustrated in full and dotted lines in Figs. l and B, the pawl K is pressed by the spring for the nose 'of said pawl to enter the notch 7'2 of wheel j', whereby the time train acts through the arbr h and arm K to impart movementto the pawl and the notched wheel for t-he4 purpose of turning the gear y', and thereby imparting movement to the carriage and the card retaining elements thereon. With the parts in the starting position at the beginnin of a working day say at 7 a. m., the wor an inserts a card into the machine in the following manner: The card is turned face down to start, or in the position shown in Fig. 7, the notched corner of the card engaging with the iinger f of element E, whereas the. opposite edge of the card is in contact with the upstanding end of element E', whereby the card is positioned for its respect-ive edges to engage with the respective members E E. TheV card is inserted below the cover plate, over slot b and below the plunger and the detector bar, after which plunger head c4 is struck a forcible blow, it being assumed that the card is properlypositioned in the machine. The downward movement of the plunger forces the die or punch C through an edge portionof the card and opposite to the time at which the card was inserted and, simultaneously with this downward movement of the plunger, stem N acts upon the detector bar M so as to produce perforations .2,3 in the card along the index line .e2 thereon. iVith the card inserted'face downward in the starting position, the punch or die C producesf'a recess w in the marginal portion of the card` and the card having been properly punched the workman re moves it from 'the machine and carries it away with him. it wiil he understood that the worlnnan is assigned, a piece oi work at the beginning of the day and is given one of the record cards, on which. the date job number, and other data-'should be written. Having punched the card in thefmanner and Jfor the purposes described the workman carries it with him and proceeds to work on the assigned joh. Now wl the work on the joh is completed w an proceeds bach to the machine and in its the card for the second punching operation as follows: The card is piaced on top of the machine thrust beneath the cover B so that the iirst punch or recess w will engage with the part f of element Thisfpartf determines the position ci the card with respect to the punch for the second punching operation, and, accordingly, the card is to he inserted in such manner that the part f will sub'- stantiaily till the irstrecess w produced in the card. rihe guide f being reversed to the punch, ohviousiy, the card cannot be insert ed the second time in the same position as the first insertion. and stiil bring the recess w int-o proper Contact with guide f; accord- `ingly, the card at the second'ins'ert-ion is to be reversed in position .so as to secure 'the desired result. The card positioning member having been advanced by the time train durin',5 the time intervening the rst and secon insertions of the card, it follows that the card when inserted thesecond time into the machine will occupy a diiierent position to the punch mechanism from that which it occupied during the first punching operation. New when the punch is operated to produce the second recess w in the card, said second recess w occupies a reverse posit-ion to the rst recess w, and the amount of elapsed time will be indicated between -the end of the card and the second recess io punched in the marginal portion of said card. The card having been punched for the second time, it is removed 'from the niachine and it serves as the basis for the accounting of the value of the 'workmans wages.

if desired tlie workman may be supplie-d with `a card for eachjoh of work, and when the particular job is completed by that particular workman said card is turned into the auditing department for the purpose of keeping a record of the cost oi' the work and the time devoted by the workman thereto. in this connection attention is called to the fact that by providing the card with a wage scale, the value of the time on cach job will be computed. automatically by the punching or recessing operations, ior thc reason that the wage value will be indicated in the scale at the same time that the scalo .e indicates the elapsed time. But as the worlnnen are paid at different rates per hour, and as it may not he desirable or other workmen to iio comme '7 learn the Wages paid to a particular ivo-rl;- man, the cards may not be provided vwith wage scales, in which event one standard card ivith the elapsed time scale will he used, and these standard cards will he supplied to all worlnnen. The card provided With the elapsed time scale and to be punched by the operation ofthe machine will attord the basis for the calculation ot' the value of the work or the u'orlnnans wages, for the reason that the cards when punched and delivered to the audit-ing' department can be placed in such relation to the scales on certain charts as to rapidly7 and accuratelv7 calculate the wage value tor the particular time devoted to the job.

Again, provision maybe made on the cardv for indicating thereon the ditlerent jobs oi Work which are assigned to each worlnnan for a full. days time. This requires the Workman to denote the numbers ot the different jobs and the character of the operations performed thereon, but the card should be punched onli7 at the beginning ci the day and one or more times according,- as the .vorlr on the lich is completed and the work on another job is commenced.

As hereinbefore indicated the ca rriage with the elements E E is impelled bv the time traintor a predetermined distance and at predetermined intervals controllable by the escapex'nent mechanism, which in turn is under the control of the master clock' when a series of recorders are employed on the same circuit, but the total distance traveled by the carriage and the elements E E thereon is equal substantially to the length' ot' the card to be inserted in the machine. Now when the carriage reaches the limit of its movement in the direction in 'which it is adapted to be impelled by the action of the time train, the arm K and pawl l malte practically one complete reifolution, and during this travel ot the carriage the spring; li is placcd under tension by the power ot main spring Gr. -s the carriage reaches the limit of its movement at the end of a Working' dav the 'heel Z of pawl K egages with lined post Z. thus throwing' the paivl out et the notch in`Wheel. j, whereupon the notched Wheel is disengaged or inicoupled 'from the time train and the spring li becomes effective in turning thespooh and with `the parts j', in a reverso direction tor the purpose of returning' the carriage to a starting position. at which time the notched ivheel will bc turned by the springa L to a position ready -t'or the nose of the pawl K to again engage with the notch y", thereby restoring the parts to a iiosition rcadv to begin operation for the next da):

lt is desirable more or less 'frequently to equip the. machine with mechanism tor in dicating on th(` cards overtime on the par ol" llicavorkman, as for example, the length ot time which the Workman may remain at- Work aittcr the close of the Working day and prior 'to beginning the Work for the following` dajf. The mechanism for this purpose operates in conjunction with the time train, the. carriage, the releasing' device, and the resetting device hereinbet'ore described. In Aaddition 'to the mechanisms and devices described, the machine is equipped With the parts illustrated in 9, 10 and l1 ot the drawings. in which figures K designates the arm with the pawl KQ J is the spool provided 1with the notched Wheel j and the rear L the spring attached to the spool and anchored at one end on the fixed post Z, and il is the rack on the carriage which is equipped with the card positioning members E E, all as hereinbctore described* O designates a second arm positioned next to arm K, said arm O being at an angle to arm l, and being fixed by the screw 7u to the lower part of arbor fi, whereby the arm G is adapted to operate in conjunction with arm hf. On the arm O is carried a secondpaivl l? pivoted intermediate its ends by a pin p to the arm. The nose of the paul is provided with a stud p which is arranged to contact with the peripheral edge or' the notched Wheel j and at certain times to enter into the notch 7'2 therein7 for the prupose ot making the arm O and pawl P act as a second means for connecting' and disconnecting the time train with the spool Cl. Said second pavvl P is under the controll of a spring` p2 which acts' to retain the studn in contact with the notched Wheel j or the notch jg therein, and the heel of this second paivl is adapted for engagement with `one or the other of a 'group of notches or teeth provided in an 'escape wheel Q., the

latter beingl carried on an arbor g mounted in the traine F. The. escape Wheel is held 'trii'tiomillir on the arbor so thatI 'said escape ivheel Q is normally at rest. but it is adapted to be operated or turned at intervals by the movement of the second pawl post and in contact with it`for the purpose of present-ing` one ot the two notches in each pair in the path of the heel ot the secondld'vhen a machine equipped'ivith the over-A timemechanism is in use. the. pawl K acts to connect the tune tram with the notched .vheel` y" on spool .l in gear with the rack of the post Z so that the pawl K- Will be disengaged Yfrom the notched Wheel and. thel which time the arms K 0 and the pawls K engages With the nose of paivl Ki. The time ing position, all as hereinb described; but at this time the olloivi i cperat ons of the overtime mechanism taire place: r'he escapement ot the time train operates tor a few minutes or other short-perionfot time so that the patri ii will be moved idly, but the end of this idle period intervening the end ofthe working day and the beginning of the overtime period, the heel oi: second pai/vl P enters the deep notch et one groove in the escape Wheel, whereupon the spring acts upon said second pavvl to turn it on the pivot p so that the stud p of said second pawl enters the notch j@ of wheel. j', whereby the arm O, the second pawl P, and the notched Wheel y, operate conjointly in connecting 'the time train with the carriage through the geared spool l Non, the escapement is actuated by the master cioclr, or by other escapementmechanism, so that the time train rotates the train of arbore in or der 'to impart movement to 'the carriage at predetermined intervals and for predetermined distances, and this movement of the carriage with the card positioning elements E E enables the machine4 to be used after the working hours "or during the overtime period for the purpose of punching the time card or cards which are to be inserted into the machine. The mechanism acts as described to impart movement 'to the carriage during the overtime period or until said car-y riage again y approaches the limits of its movement toward the finishing position, by

spring L tviii return the car ieee to startl l l l P will be turned nearly one complete revolution. Now, when the heel of the pawl P is brought into engagement with the fixed post l', said pawl is turned on its pivot and the stud p is Withdrawn from the notch j? in the wheel j', whereupon the spring L becomes eii'ective 1n turning the spool. for a limited angular distance, and the carriage is moved for a short distance toward the starting position; but before said parts can be restored to said starting position :tor beginning a new days work, the pawl K is restored into engagement with the notched Wheel j in the following Way Upon the disengagement ot second pawl from the notched Wheel, the spring L turns the Spool backward until the notch y'2 ot' the wheel y train now -operates for a period of time inthe beginning of the succeeding day period so that the mechanism remains idle so far as imparting movement to the carriage is con cerned. During such period, the arms K G are turned and theheel oi pawl P is brought into position 'for engageu'ient 'with the shirt-u low notch in the escapement Wheel and the f heel of the pawl E. engages with the nxed 1 post l so that by the continued operation of the escapement, he paivl ii will become disengaged/trom the notch of Wheel y", thus allowing the spring li. to reset the carriage to the starting position. The escapement and time train now act periodically to turn the arms to a certain angular position. for the purpose of shitting the pavvi U by Contact with the escape Wheel out of engagement with said escape Wheel, the pavvl K being moved iar enough around for its nose to enter the notch et Wheel j', thus restoringthc arm and pavl it to a position tor again connecting the time train with the rack through the actiorroi2 the spool J when the hour arrives Jfor beginning the succeeding l" 's Werl?`n ff hns iuily `described the invention, wha" l claim as new, and desire to secure bu Letters iatent is:
